Thanks for this. I've reported it, but since CU7 is coming soon, I really don't expect action on it.

After installing and rebooting I found that the Content Index State was failed on all the DB's on a server. When I did ran this command: Get-MailboxDatabaseCopyStatus -Server $server | fl name,*index* It showed that service "Microsoft Exchange Search Host Controller" was not running. Looking at that service it was set to disabled, but the servers that had not been patched showed it automatic and running. So I set this back to automatic and started it. After a few mins the indexes went back to healthy and I was able to move the DB's back to mounted state. Doing some searching it looks like other CU's have done this in the past. Also found that this service was also set to disabled by the patch so it needs to be set back to automatic. Tracing Service for Search in Exchange Looks like MS has a bug in the installer that it does not set the state back to the correct setting after the patch is applied. js
